In 1974 the Warrens were summoned to a home in Harrisville, Rhode Island, where allegedly the angry spirit of Bathsheba Thayer was haunting the family, the Connecticut Post reported. It became the basis for “The Conjuring” series, the newspaper reported.

The following year, the Warrens visited Amityville, New York, to investigate the home where Ronald DeFeo Jr. murdered six family members. That evolved into 1979’s “The Amityville Horror” movie, followed by sequels and prequels.

“The Warrens believed that the suffering there had left the property with a very negative energy and dark history,” the psychic research society’s summary of the case said. “And that such a negative history was a magnet for demonic spirits and the preternatural.”

The case raised their profile as paranormal investigators, the Times reported.

Lorraine Rita Moran was born in Bridgeport, Connecticut, on Jan. 31, 1927. She said she began having clairvoyant experiences as a child, the newspaper reported.

She met Ed Warren when she was 16, and they were married in 1945.

According to Gerald Brittle’s book, "The Demonologist," the couple investigated more 3,000 paranormal and supernatural disturbances, CNN reported.
